Which direction is relative to magnetic field? The direction of the force due to a magnetic field is perpendicular to the direction of motion. distance away from the wire, and is called the permeability of free space. Magnetic fields are measured in Teslas(T). Why are iron atoms affected by magnetic fields? Iron atoms are ferromagnetic […]

How do you explain weather and climate? Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, is the average of weather over time and space. We hear about weather and climate all of the time. Most of us check the local weather forecast to plan our days. Which season is the most windy? Of […]

Does melting point increase across a period? Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. The atoms also get smaller and have more protons as you go from sodium […]

How many minutes does it take to drive 16 miles? There are 60 seconds in a minute so 0.4 of 60 is 24. In plain English, It would take you 38 minutes and 24 seconds at 25 miles an hour to drive 16 miles. How many minutes does it take to drive 17 miles? the […]

What is magnet and types? Permanent magnets are magnets that retain their magnetism once magnetized. Temporary magnets are materials magnets that perform like permanent magnets when in the presence of a magnetic field, but lose magnetism when not in a magnetic field. Below we breakdown the various types of magnet available. What are the main […]

Does changing current affect voltage? To answer this question, the relationship between the voltage and current variables given must be specified. and thus that the current will change proportionally with the voltage. and thus the current will change exponentially with the voltage. Does higher voltage draw less current? If the voltage out is twice that […]

What is the egg drop problem? Egg dropping refers to a class of problems in which it is important to find the correct response without exceeding a (low) number of certain failure states. In a toy example, there is a tower of n floors, and an egg dropper with m ideal eggs. What does Ojo […]

When a spoon is in a glass half full of water Why does the spoon look like it is broken in the middle? It is refraction due to which we saw spoon broken near water surface. 1. If you put a coin inside glass of water and view it from the top then coin appears […]

What force is needed to give a 2000 kg car? The net force needed is 4000 N . How long will it take to walk 10km? 90 minutes to two hours How many minutes is 25 miles? It is possible to go 25 miles on the interstate in 30 minutes. It can take anywhere from […]

Does more water make plants grow faster? Water helps a plant by transporting important nutrients through the plant. With outdoor plants, you can’t control the plants getting too much water if your area gets a lot of rain, so you need to make sure that the soil has the proper drainage, because too much water […]
